in place by breaking' o'neof the parts`,'and' which will be siuiple,'cheap, strong, and vdnrable.

The accompanying' draw-ings illustrate the preferred forms of the mechanism by which I attain said object.

Figure lis a front elevation of the entire device. Fig. 2 is a vertical section of the lock on the line 2 2, Fig. l. tion on the line 3 3, Fig. 1. 4Fig. 4 is a crosssection along the line 4 4, Fig. l, showing the parts as they appear when viewed from beneath. Fig. 5 is a front elevation of the pin or bolt with its lower end and the top of its head broken away, and Fig. 6 is a rear elevation of the slide used to close the front of the lock-case. l

Similar letters refer to simil ar parts th rou ghout the several views. j Y

A is the lock-case. Itis preferably attached in place in a substantially vertical position by screws or bolts Ct d, passing through lugs or projections ce a', extending from the top to the bottom of the case. The heads c2 of the fastenings a are preferably countersunk in the lugs a', substantially as shown. The front plate CL3 contains an opening a4. The bottom a5 of the case contains a transverse slot a6, and substantially vertical bolt or pin holes a7 and as pass through the top and bottom of the case.

Vithin the casing A a lining B is shown, consisting of sides 1J 19, a top piece 19', a bottom piece b2, a vertical cross-piece 193, and brackets 174 194, in which bearings 125 115 are formed for the trunnions of the tumbler, hereinafter described. The rear edges of the sidesb 19 of the lining B may rest against the side of the Car or other structure to which the lock is attached, and the front edges may rest against Fig. 3 is a cross-sec-V tlie'casing A. Said'front edges of the sides 19 are preferably rabbeted at 1)6 1), so as to form slots 177197 between them and the casing A; A transverse slot 128 is formed in the bottom 122 of the lining'at its front edge, and the bottom of the lining is rabbeted at 1). The slot 19S is preferably narrower thanthe slot a through the bottom of the casing A. The top and bottom of therlining B are pierced by bolt-holes 1310 and bm, which, when the lining is in place, register with the bolt-holes CLG and a7 through the casing. As will be obvious, the case A and lining B above described may all be made of one 'piece instead of two, and whether made in one or two or more pieces the operation of the lock will be the same.

C is a pivoted tumbler. It is preferably provided with trunnions c @which turn in the bearings b5 115. It is also provided with two projections c and c2, whose exact form is not material. They may be formed as shown in the drawings, and are preferably so located with reference to the pivotal point as to prevent the tumbler from being forced out of engagement either bya pull on the pin in the absence of the seal D or by a pull on the seal inthe absence of the bolt E; but this is not essential.

D is a seal used to close the opening a4 in the lock-case A. It is preferably provided with a lip CZ, and is shown notched at c1.

The top d2 of the notch is preferably at right angles to the face ofthe seal, so as to form a shoulder or stop. The seal is inserted in position by pushing it up through the slot 0, in the bottom of the lock-case and the slot 198 in the lining B, while its edges occupy the slots 197 117. When pushed up in this manner, the projection c of the tumbler C is pushed out of its path and the tumbler caused to make a partial revolution; but when the sealD is pushed up far enough to carry the top C12 of the notch c1 above the projection c' the latter is forced by gravity to drop into the notch, and thus engages the seal D. The lip d of the seal enters the slot a6 in the bottom of the casing, and when the seal is in place its bottom preferably comes about flush with the lower end of the lock-case. The lip c1 prevents anything from being passed up into the IOO interior of the casing through the slots a and iis. As will be obvious, the lip d of the seal D is not an essential element, though a desirable one, and when it is understood that the only object in having the inner face of the seal D notched at d is to provide a part, such as d2, which will come in contact with the projection r when an attempt is made to push or pull the seal D downward, it will be seen that either one oi a very large number of different weil-known forms of stops or projections might be substituted for the one shown without in any way changing the' mode of operation of the device, and I desire not to be limited to the notch described, but to cover all equivalents. The seal D is prcferabl y made of a brittle material-such, forinstanee, as cast-iron or glass. Upon the outer face of that portion of the seal D which comes opposite the opening af* ot thelock-case any desired iden tii'yin g letters and words may, where the seal is of eastiron, be east thereon-such, for instance, as the name of the town from which the car comes and the initials of the road which received the load from` the shipper.

E is a bolt having a head e, and whose lower end is lettered e'. It is preferably either rectangular or oblong in cross-section; but it is not essential that it should be so. The bolt E is preferably notched at e2, so as to provide a shoulder ewhieh will engage the under side ol the projection c2 of the tumbler C when an attempt is made to withdraw the bolt. Vhat has been said concerning the notch in the seal D is equally applicable to the notch in the bolt. I do not desire to be coniined to the use of a notch for providing` a shoulder or stop for engagement with the projection c2 of the tumbler C, but desire to cover all equivalents. The bolt E preferably passes down through the lock-ease A, as shown, and when in place its head e preferably rests upon the top of the ease A, while its lower end projects down through the bottom of the case A and passes far enough into or through a staple F to prevent the withdrawal of the hasp G, and when in that position its head e guards the head a2 of the screw or other fastening behind it, while the lower end guards thehead of the fastening a, passing through the lower lug a of the case. As will be obvious, however, it is not necessary to the operation of the lock that the head of the bolt orpin E should project above the top of the ease A, or that it should be removable through the top of the case, though I prefer the form of device shown.

A ear may be locked with my device as follows: The car-door being closed and the hasp G being in place, the bolt E is pushed down into position and through the staple F. Then the bolt E is inserted, the tumbler C swings to one side, so as to permit it to pass; but when it is far enough down, the projection c2 is caused by gravity to swing into the notch e2 of the boit, and in the form of my opening a4 in the case and disengaging it by pulling the projection c2 back far enough to allow the shoulder c5 to pass. To make the locking complete, the seal Dis next pushed up into position. The projection c' ol the tumbier C gives way before it and permits the top of the seal to pass. As soon as the shoulder d2 passes above the projection c', however, the projection c' is caused by gravity to drop into the notch at cl', and it the seal l) is then allowed to drop the shoulder d2 comes to rest upon the top of the projection c. there the projection c is formed so that there is not room for it to turn down out of the way of the shoulder di, as it is in the construction shown in the drawings, it is impossible when the seal D is locked to withdraw it without either breaking it or taking the lock ol't the car, even where the projection c2 does not bear against the bolt E or an equivalent stop; but where it does bear against the bolt E the bolt E operates as a stop to prevent its turning, whether otherwise revolubie out ol' engagement or not. The seal D, on the other hand, would prevent the disengagement of the projection c2 from the shoulder e3 of the bolt E, if it were otherwise possible. lVhen it is desired to open the car, the seal D is broken by a blow or otherwise. An opening being thus made, the tumbler C is caused to turn so as to disengage the bolt or pin IC, which may then be lifted up high. enough. to permit the disengagement of the hasp. The broken pieces of the seal are also removed and a nenr seal inserted when the ear is started out again.

I claiml. The combination in a car-seal lock of a case having an opening therein, a sliding seal closing said opening, and a pivoted tumbler, which turns to admit said seal, and is caused by gravity to engage and lock it, substantially as described.

2. The combination in a ear-seal lock, ot' a case having an opening, a seal closing said openin g; a reciprocating bolt; and a pivoted tumbler, which automatically locks said seal and bolt, substantially as described.

3. The combination in a car-seal lock of a case, having an opening in one of its faces; a seal, closing.,r said opening, which has a lip along the inner side of its outer end, which rests in a recess when the seal is in place 5 and a pivoted tumbler within said case, en gagn g and locking said seal.

4t. The combination in a cai-seal lock, of a case having an opening in one face; a seal having a lip along the inner side of its lower IOO IIO

end, closing said opening; a bolt passing throughsaid case, having a head at one end restingagainst the case, and at its other end projecting beyond the case; and a pivoted tumbler Within said case, automatically engaging said seal and bolt when they are in position; substantially as described.

5. In a car-seal lock, a case having an opening through one of its faces, and Within said case the tumbler C 5 and a pivotal support for saidtumbler; the axis upon which the tumbler turns, being substantially horizontal and said tumbler C having a part c Whose Weight tends to force it outward toward said opening, and another part c2, which gravity tends to force inward far enough to project Within a vertical plane parallel with the axis of the tumbler and passing through said axis, substantially as shown and described.

6. The combination in a car-seal lock of a reciprocating bolt; a stop positively limiting the movement of the bolt in the direction in which it is shot; a pivoted gravity-tumbler automatically engaging said bolt when shot, and preventing its retraction; and means making it impossible to disengage the tumbler by revolving the bolt; so that, when the car-seal is locked the bolt cannot be unlocked 4 either by turning it or moving it longitudinally.

7. The combination in a car-seal lock, having an opening through one face of a sliding seal, closing said opening and having on its inner side, a stop and a pivoted tumbler,whose pivotal point is nearer the end of the case, from which the seal is inserted, than said stop, and rests against said seal between said stop and the opening through which the seal is introduced, at an angle which prevents its being turned out of position by an attempt to remove the seal, substantially as described.

8. The combination in a car-seal lock of a bolt having a stop on one side thereof; and a pivoted tumbler, Whose pivotal point is farther from the point of the bolt than said stop, and which tumbler rests against such bolt on the side of said stop, farthest from the point of the bolt, at an angle which prevents its turning, to permit the passage of the stop,

when pressure is brought to bear upon the end of the bolt, substantially as described.

Witness myhand this 22d day of June, 1895.
